Antonio Williams, 49, was found fatally shot in his Houston residence on November 12, 2013. Investigators characterized the killing as a targeted attack and noted there were no signs of forced entry, prompting consideration that Williams may have known his assailant.

Neighbors were interviewed and evidence was collected, but no arrests were announced and the case remained open. The Houston Police Department appealed to the public for information as the investigation continued amid limited witness accounts and few clear leads.

Did anyone in Houston know Antonio Williams or see anything in his neighborhood around November 12, 2013, that might help investigators?
